lowing` in a Hpeeiti 'ation 'this invention related to woven textile taln'ie tor ase as ninlorella covers.

The essentials ot' a taht-ic lor nlnhrella covers are. tirrit, that it shalthe Strong and tltn'ahlc throughout, shall he apahle ot .vith:=tandtheV the train cn the wett or till ing' incident. lo itsI attachment to the, trame ot an mnlirella and tr: eontinned train when f stronger threads or varno tor the required the tnnln'ella is raised; and farther that` that. portion ot' the tahrie which in a completed tn'nln'ella rover constitutes the edge shall he reintioreed in rehpt'et ol the warp in lorder that it may withotand the sndden strain placed npon it in raising; an innhrella and the continuino) I#train to which it. is -@Jilhjected dtzrine; the whole time an ninln'ellaiS; raie-ed, it heine; neem-:nary in order to meet the requirements that when an umbrella` is rai--ied the entire covering,c he nnder tension in ordeil to present the desired and universally required apmaranee. 'lhe atrength neerss -ary at the edge ot' the cloth has usually heen ejiven either ln' hemniineT or hy forinineja selvaffe edge on it. llennningl involves a largrc and needleen expr-me and is not an presentahle as a :ielvnge edge and therefore the latter is; moet, ie'ed Vl'or the pnrijiose. il'hen in a taht-ie ot' which the warp i5 ot' with. the edge is thioltemd in order to strengthen it hy increasing the ninnher or :dye ol the silli thrmlh4 ot the warp a gr'reat inereawc in tho cost olf the material results. and as the Hill( is neither Strong nor dnrahl-e it qliieltly hrealtssl or wears ont in nso. ln order to moet the reqnirenients` ot cloth for umbrellas ot' higher (Trades it munt have more or less luster, and

.atrength and appearance, and which by` its peculiar formation .shall not only present the retplred strength to withatand strain in the diret-tion in which it is most imposed in attaching it to an nmhrelta traine and when an llmln'ella in raised, lnlt` which `shall he possewted ot:` additional strength in tho part which when the t'ahric i5 used all al1 nmhrella cover tornei the edge theredt'.

With thin` ohief't in view the invention convicts eaaentiall'v otE a `t'ahric t'or the purpoc dceerihed wherein the warp is comptmetl principallyY ot lie-ht, pret'crahly las? [Vous threadsM the wett ir; ot strong threads or varn pret'erahlv eott'on yarns, and the sclvae'c edgfjes are t'crmed hy arranging width at )ach side ot the lighter threads constituting the principal part ot the, warp, with which are woven the stronger threads or varns constituting the welt or filling.

ln the aeoinpanying drawingl Figure l reprewents a length ol cloth made in ac'- t-ordani'e with my invention, on which are. indicated hy dotted lines the ents which are made to torm cetions ol lnnhrella covers;

Fig. 2 re|nesent n section ot cloth ont from.

tht,I strip and denigned to `l'orm a portion of an nmhrella cover; Fig. 3 is a view Showing the torin arnnned hy the section when it is joined to other corresponding set-tions aty its edges, and when it its attached to a notch ring; and in stretched and attached to the endl; o l' nmhrella ribs; Fig. lis a side View ol a completed ninhrella of which the i111- proved Ytahrie torinav the cover; and Fig. 5 is a view on an enlarged `scale ot a portion ot the l'ahrie shown on Fig. 1.

ln weavingr the cloth the warp lis arranged in a loom ot: ordinariy construction, the` nmnher ot warp threads utiliz/.ed in the hodv of the cloth heine; governed hy the l duality ol1 cloth to he produced. The warp in all cases the fabric n:-:ed t'or ein-erh' most y l meh as cotton will impart a distinct luster,

he as thin as practieahlc in order not to presenty a bulky appcaranee when the innorella is :Folded or rolled. The m'oat available way-to ohtain these ends is h y the. use of sill; in the lahric.

The object of in y invention is to prodnea a fabric which Shall he cheap and shall moet. all the requirements ol lightnes,

preferably employed h v me is of Isilk threads ot' a nnmher which when woven with a weft or tilting' ot other, non-hlntrons, material to the completed t'ahrie. (ln lach side of thi,I warp threads toi-ming the principal part ot' the warp are arranged threads; or 'arn 2 which are stronger or larger or more t-losel)v rronpcd than thrm- Forming' the hody of the warp. '.lhev are prelei'a'hliy ol niereerized eotton or similar htrong inexpenfsive l material and of' a number per inch', Which .is larger than that of the silk threads of the body of the Warp employed.

The weft threads employed are of some cheap material preferably for purposes of strength being of cotton yarn. In the weaving of the cloth the body 3 'thereof is preferably woven thread for thread of warp and vveftv in order to present a smooth uniform appearance, but the'selvage edge i may be woven in any suitable rwayto give any desired appearance tothe edge of the cloth, as for instance'the edge may be woven to give the appearnce of ottoman silk, the warp threads to overlie any number of the weft yarns' to present ribs ofthe desired width. The ribs so formed may extend either at right angles to the edge of the fabric, or `at any other angle thereto.

`Triangular sections are ciit as indicated by the dotted lines in Fig. 1 across the fabric Woven as described, and the smaller ends of the sections are placed in contact and the edges of the sections sewn together throughout the entire length, to form umbrella c'overs. The Width of the fabric is normally i shorter than the length of the umbrella ribs to which the cover is to be attached. In attaching a cover to a frame the upper portion is first secured to the notch ring of the umbrella and the material is then tightly drawn and stretched and sewn to the outer ends of theribs. The strain thus imposed is necessary in order to give a taut appearance to thepcloth, in the finished article, and this Whole strain comes upon the weft or 'filling of the material. WVhen the cover made as described is connected by thread or other'means of attaching it to Athe ends of -l the ribs the thread passes through the outer edge of the cloth, and the necessity for made for4 the purpose, its appearance when composed of a silk Warp and a cotton weft is similar to silk, and by reason of forming the thickened edge entirely of cotton thatv part is `given the necessary strength and wearing quality, and the costof the fabric is less than if the edge be strengthened in any other way.

Having thus described my invention, what I claim as new, and desire -to secure by Letters Patent, is:-

l. As a new article of manufacture a fabric for umbrella covering the body of which is composed of silk warp threads and cotton weft yarns interwoven with the Warp threads, the edges of the fabric being composed of cotton warp yarns interwoven with the weft yarns.

2. As a new article of manufacture a fabric for umbrella covering the body of the warp of which is composed of thin silk warp threads, the edges of the Warp being of cotton warp yarns coarser than the silk threads, and a weft or filling of cotton yarn l interwoven with the warp formed asA described.'

-In testimony whereof I atiiX my signature in presence of two witnesses.
